خلاصه

Tadalafil markedly potentiates the blood pressure lowering effect of nitrates, including sublingual nitroglycerin. The combination can produce profound, refractory hypotension, syncope and myocardial ischemia, and tadalafil's long half-life means the risk persists for days after a dose.

معنای این تداخل به زبان ساده

Nitroglycerin sublingual and Tadalafil are not normally used together. Taking them at the same time is expected to cause harm or make one of them unsafe, so a different medicine is usually chosen for one of the two.

سطح شواهد: High

چرا رخ می‌دهد

Nitrates raise cGMP via nitric oxide release while tadalafil blocks cGMP breakdown by PDE5, producing excessive additive vasodilation.

اقدام لازم

Do not use together; nitrates must not be given within 48 hours of the last tadalafil dose. If chest pain occurs within that window, seek emergency care and use non-nitrate measures under medical supervision.
